Baird established his species on a single specimen obtained dming the Ross 

 Antarctic Expedition; it was without a tube, and was characterised by its operculum. 

 Mcintosh (1870, p. 322) compared it with a specimen collected by the Venus Transit 

 Expedition to Kerguelen, which, although it lacked the operculum, was in its tube. 

 He satisfied himself that the two are identical. 



In 1897 Ehlers placed Baird's species as a synonym for S. vermicularis, and 

 suggested that Mcintosh's var. margellanica should be included. But in 1912 Ehlers 

 makes it a distinct variety, the tubes of which, he showed, are linked on with the type 

 by a number of intermediate forms, in some of which even the everted lip, upon the 

 possession of which Baird founded his species, was lacking.
